NFC payments have seen a slow but steady rise here in the US in the past few years. While far from achieving global penetration, systems like Android Pay and Apple Pay have actually become pretty commonplace in many large retail chains and even some small businesses via checkout services like Square in America. I'd say I'm using Android Pay, personally, about half the time I'm interacting with a card terminal these days.
But I know it's not like that for everybody, and that other systems like Samsung Pay, or some specific to certain banks in some countries, do exist. So I'm curious if you use NFC (and/or MST) and, specifically, which system you use.
